[Embodiment 1]
As shown in FIG. 1, the erroneous charging prevention system 1 is transmitted from a chemical container 3 to which an RF tag 2 is attached, a chemical tank 4 into which chemical is charged from the chemical container 3, and the RF tag 2 of the chemical container 3. An RF signal sensor 5 that reads a signal to be read, a determination unit 6 that determines whether the medicine to be put into the drug tank 4 is correct based on a reading result of the RF signal sensor 5, and a notification unit 7 that notifies the result of the correctness determination .

  The RF tag 2 includes an antenna, a control circuit, and a memory, and information on the medicine in the medicine container 3 (in this embodiment, the kind of medicine) is recorded in the memory portion.

  The chemical container 3 includes a removable lid 3a and a main body 3b, and the RF tag 2 is provided on the lid 3a. The RF signal sensor 5 is provided at the place where the removed lid 3a is placed.

  In the vicinity of the chemical tank 4, an approach detection sensor 8 (piezoelectric sensor) that detects the approach of an object to the chemical tank 4 is provided. When an operator holding the medicine container 3 approaches the medicine tank 4, the approach detection sensor 8 detects the approach, and the RF signal sensor 5 is activated in response to this detection.

  The activated RF signal sensor 5 reads the signal from the RF tag 2 provided on the lid 3 a and transmits the read result to the determination unit 6.

  The determination unit 6 performs correct / incorrect determination on the medicine to be put into the medicine tank 4 based on the received reading result. Specifically, the information on the medicine read by the RF signal sensor 5 (in this embodiment, the kind of medicine) is compared with the information on the medicine recorded in the determination unit 6 in advance. If they do not match, it is determined to be wrong. Further, it is also determined to be erroneous if the determination unit 6 does not receive the reading result for a predetermined time after the RF signal sensor 5 is activated due to the reason that the RF tag 2 is not provided on the lid 3a.

  The notification unit 7 includes a green light 7G and a red light 7R. When the result of the correctness determination received from the determination unit 6 is positive, the green light 7G is turned on and the result of the correctness determination is incorrect. The red light 7R is turned on. The operator can recognize whether or not the medicine he / she wants to add is appropriate by looking at the behavior of the notification unit 7.

  In the conventional method using a bar code, it is necessary to add an operation of reading a bar code in order to determine whether the medicine is correct or not, which has led to an increase in work time. On the other hand, the erroneous input prevention system 1 can perform the correct / incorrect determination of chemicals during the normal input operation of the worker, and it is not necessary to add a new operation, so that the operation time is not greatly increased. The correctness / incorrectness of chemicals can be determined.

  Further, in the erroneous charging prevention system 1, the RF signal sensor 5 is configured to be activated when an operator holding the chemical container 3 approaches the chemical tank 4, and does not need to be activated at all times. Power saving can be realized.
